Simon said: “Battery memory effect is about batteries remembering remaining charge if you don’t let them go all the way to zero too often. So a battery frequently charged from 20% to 80% might ‘forget’ about the 40% that’s left uncharged (0-20% and 80-100%).

“Sounds crazy but that’s sort of true - but only for older nickel-based (NiMH and NiCd) batteries, not the lithium-ion batteries in your phone.

“Lithium-ion (Li-ion) batteries don’t suffer the memory effect so you almost need to do the opposite: charge them often but not all the way throughout the day, and don’t let them drop to zero.”

What is the best way to charge my phone?

With Lithium-Ion batteries (Li-ion) it’s recommended that the battery is always kept charged above 50%. Obviously this is hard unless you spend your life next to a plug socket, which is why portable chargers are handy. If possible don’t let it charge to 100%. It won’t be the end of the world for your battery if you do but it will shorten its lifespan. Experts say a good range to aim for is keeping it between the 40-80% range.

Should I ever fully recharge the battery?

Once a month you should plug it in and let it hit that 100% mark. This will recalibrate the battery and also applies to laptops.

Should I recharge my phone all night?

With experts recommending that your phone should only ever be charged up to 100% once a month, it’s not advised to leave it charging for 8-10 hours every single night.

Some tech experts also say that you should remove your phone from its case for a long charging session as it can lead to overheating.
